Twitter Syn in MVC and C#
Step1: create application in twitter by using this
link https://dev.twitter.com/apps/new once open that will display window like this after Create you will get
1.ConsumerKey
2. ConsumerSecret
3.AccessTokenSecret
4. AccessTokenSecret
Use above keys from Below code..
Step2 : Use Keys in to you projects
Appurls.cs
public static string authentication = "https://api.twitter.com/oauth2/token";
public const string RequesttokenURL = "https://api.twitter.com/oauth/request_token";
public const string AuthorizeURL = "https://api.twitter.com/oauth/authorize";
public const string AccesstokenURL = "https://api.twitter.com/oauth/access_token";
public static string ConsumerKey="Your ConsumerKey ";
public static string ConsumerSecret="Your ConsumerSecret";
public static string AccessToken="Your AccessToken";
public static string AccessTokenSecret = "Your AccessTokenSecret ";
public static string TwitterAccountCredentialsURL = "https://api.twitter.com/1.1/account/verify_credentials.json";
public static string TwitterCallbackURL = " Your Return URL";
step3: Add one class name- oAuth.cs and write below code
Class Files for Twitter Access

using System.Security.Cryptography;

if (oAuth.TokenSecret.Length > 0)

JObject o = JObject.Parse(xml);
name = Convert.ToString(o["name"]);
username = Convert.ToString(o["screen_name"]);
profileImage = Convert.ToString(o["profile_image_url"]);
followersCount = Convert.ToString(o["followers_count"]);
noOfTweets = Convert.ToString(o["statuses_count"]);
recentTweet = Convert.ToString(o["status"]["text"]);
verified = Convert.ToString(o["verified"]);
id = Convert.ToString(o["id"]);
Session["verified"] = verified;
Session["id"] = id;
Response.Write("<script>window.close();</script>");
}
}
}
step 6: you will get repose above code if u want display u can display your view page...
